To those skilled in the art, will be clearly, processor 104,204 only is used for function is described, and they can be realized by the some processors that separate that link with different function units.For example, each fingerprint generation unit 106,206 has processor and generates step so that separately control fingerprint, and each recognition unit 109,209 has processor so that separately control identification step.
To those skilled in the art, will be clearly equally, when equipment 100 comprises recognition unit 109, need not to comprise recognition unit 209 in the equipment 200 so that save cost.Identical design also can be applied to other unit, and for example, if equipment 100 has fingerprint generator 106, then equipment 200 need not to comprise fingerprint generator 206; And if there is the unit 105 that is used to generate signal S1 in the equipment 100, then equipment 200 need not to comprise unit 205, and vice versa.In order to determine which equipment which unit should be included in, treatment effeciency and cost are the aspects that needs consideration.
Fig. 3 only is the example of equipment 200.Equipment 200 not necessarily comprises all unit shown in Figure 3.For example, can be included in according to which unit and got rid of (unshowned) unit 206,209,205,208 in the equipment 100.
Fig. 9 illustrates the audio/video content that receives TV program P1 by unit 101 duration 900 with the fingerprint that is used to generate the described first broadcast audio/video content; By unit 201 receive TV program T1, T2 ..., T6 a series of audio/video contents to be used to generate the duration 916 of a series of fingerprints; And receive each TV program T1, T2 ..., T6 a series of duration 901,902,903,904,905,906 of each audio/video content.
Because by unit 101 and unit 201 received audio/video contents are broadcast datas, therefore the content of this data is different along with the time; In order successfully to realize identification step 403, the duration 900 must not be shorter than the duration 916.
For the time started and the concluding time of duration 900 and 916, there are two kinds of situations.If come from same radio network by the received audio/video content in unit 101 and by unit 201 received a series of audio/video contents, in other words, radio network M is identical radio network with N, if perhaps this two identical audio/video contents of Web broadcast and without any time delay, then 900 time started A should be not later than 916 time started C, and 900 concluding time B should be no earlier than 916 concluding time D.In other words, the time range of duration 916 is within the time range of duration 900.
Sometimes, radio network M and radio network N broadcasting have the same audio/video content of time difference, for example, (Guang Bo – is hand-held frequently for Shuo word Shi based on the DVB-H standard, be used for mobile phone) broadcast system broadcasting compare same audio/video content with DVB – T system (digital video broadcasting-ground is used for fixing the TV machine) with delay.In the case, duration 900 and 916 time started and concluding time must consider to broadcast time delay.
For example, if network M postpones K second after network N, then the concluding time B of duration 900 must postpone K second, and in other words, the concluding time that the concluding time B of duration 900 should be no earlier than the duration 916 adds K second.Similarly, if network N postpones K second behind network M, then the concluding time B of duration 900 adds that K should be no earlier than the concluding time of duration 916 second.
